Dealership oil, yes or Nah....

[galaxy xr8]

I'm about to take my '16 Territory in to a Ford dealership for its annual service, in the past I've always supplied my own oil (Castrol Edge). But this time round I'm finding my OCD is dwindling and I can't be bothered really.

The dealership that I'm taking my car to uses Valvoline Syn power 5w-30 which is recommended for the vehicle in question.

But after reading some stories on how the dealerships or some places use bottles that have mixed ingredients (oil etc) and have crud or dirt particles in them as lets face it, the mechanics are probably over worked and under paid and it's not their car so the care factor is not all there, but thats a story for another day.

What's peoples thoughts on this, and does anyone know exactly what the refill procedure is at dealerships, do they have a certain protocol that they have to abide by so that crap doesn't get into fresh oil etc.

I am now thinking of buying some Valvoline Synpower oil in 6L capacity and just giving them that to use as I have done in the past, I'm just sick of purchasing oil and then hopping that they do actually use said oil in my car and not store it for themselves for a latter day, (even though I ask for my containers back afterwards), but its not hard to put oil in another container if need be.

Paranoid I know..
